neck lettuce

The bushy overgrowth of hair on the neckline, typically indicating it's time for a haircut. A distant relative of the Kentucky Waterfall or the Mississippi Mudflap.

It's been 8 weeks since my last haircut; my neck lettuce is ripe!

Red neck lettuce

Chips when put on a sandwich to provide crunch instead of lettuce or other vegetables.

This sandwich could use a little red neck lettuce!
